Question

I have a suspicion that I’m using the finally block incorrectly, and that I don’t understand the fundamentals of its purpose…

 function myFunc() {       try {            if (true) {                 throw 'An error';            }       } catch (e) {            alert (e);            return false;       } finally {            return true;       }  } 

This function will run the catch block, alert ‘An error’, but then return true. Why doesn’t it return false?

Answer 1

The finally block contains statements to execute after the try and catch blocks execute but before the statements following the try…catch statement. The finally block executes whether or not an exception is thrown. If an exception is thrown, the statements in the finally block execute even if no catch block handles the exception. more

The finally block will always run, try returning true after your try block

function myFunc() {      try {          if (true) {                throw 'An error';           }           return true;      } catch (e) {           alert (e);           return false;      } finally {           //do cleanup, etc here      }  }
